Welding Rubber Cable (e.g., H01N2-D, H05RR-F, or RHW) is a heavy-duty flexible cable designed specifically for electric arc welding machines and high-current applications. Its key uses include:

1. Welding Equipment Power Supply

Connects welding machines to electrodes or ground clamps.

Handles high current (100A~600A+) and intermittent overloads.

Resists sparks, abrasion, and mechanical stress near welding zones.

2. Industrial & Construction Sites

Powers portable welding rigs in shipyards, steel plants, and fabrication workshops.

Suitable for temporary setups with frequent cable movement/dragging.

Construction

Conductor: Highly flexible bare annealed copper or tinned copper wire

Insulation Options: PVC, Rubber, or EPR (Ethylene Propylene Rubber)

Sheath Variants:Natural rubber (YH type);Chloroprene/synthetic rubber (YHF type)

Alternative options: PVC or CSP (Chlorosulfonated Polyethylene)
